TX750 problem?

[magoozle]

Hello there :)

 

I've been happily running my system on a TX750 for about 18months now with an ATi 4890HD, last week i bought a new GTX470 to replace it.

 

Now it boots up fine but will black screen and reboot every so oftan, i didnt consider the psu at first and RMA'd the card but they sent it back saying no fault found.

I've done a very basic volt test on the psu (i only have an analogue voltmeter)

the gpu feeds show approx 14v, and the molex's 14v/4.5v (unsure if this is too high?)

 

the system works great with a crappy old 8800gt, but soon as i try to play metro or another demanding game it dies on me.

 

Any thoughts?

 

thanks

James

 

**edit** i also reformatted the comp fresh incase it was a driver issue swithcing from ATI to nvidia, no difference. it also makes no difference if i run stock clocks instead of my OC.

If the card has already been replaced and the board works fine when running the 8800, then lets go ahead and try getting the PSU replaced. If its not those components, and its not software related, then the PSU is the most likely cause.

 

Request an RMA
